We have a bridge in Niagara Falls like that and a couple in Buffalo. Growing up we always saw accidents there. The Falls bridge is under the Grand Island bridge getting on the Robert Moses expressway towards downtown. It looks inviting as a direct route. They only marked it with a sign saying no commercial vehicles.
Bus drivers and truckers ignored or didn't see this sign and hit the bridge repeatedly coming around a tight turn taking them under the bridge they just exited. I always wondered why they wouldn't have a clearer sign saying low bridge or danger!! in bright yellow color or similar??
Many a truck top got peeled off there. The height was marked well on the sign.
